132-RGB X 176-DOT 1-CHIP DRIVER IC FOR 262,144-COLOR TFT-LCD DISPLAY
INTRODUCTION
Preliminary
The S6D0114 is 1-chip solution for TFT-LCD panel: source driver with built-in memory, gate driver, power IC are
integrated on one chip. This IC can display to a maximum of 132-RGB x 176-dot graphics on 260k-color TFT panel.
The S6D0114 also supports bit-operation functions, 18-/16-/9-/8-bit high-speed bus interface and high-speed
RAM-write functions enable efficient data transfer and high-speed rewriting of data to the internal GRAM.
The moving picture area can be specified in internal GRAM by window function. The specified window area can be
updated selectively, so that moving picture is able to be displayed simultaneously independent of still picture area.
The S6D0114 has various functions for reducing the power consumption of a LCD system: operating at low voltage
(minimum 1.8V), register-controlled power-save mode, partial display mode and so on. The IC has internal GRAM to
store 132-RGB x 176-dot 260k-color image and internal booster that generates the LCD driving voltage, breeder
resistance and the voltage follower circuit for LCD driver.
This LSI is suitable for any medium-sized or small portable mobile solution requiring long-term driving capabilities,
such as digital cellular phones supporting a web browser, bi-directional pagers, and small PDAs.
